which mattress type is better, turnable or no turn?

Definitely turn-able! Once the no-turn mattress is wore out, it's done! I think they are making more "no-turns" so that they can increase their sales in the long term. We had to get rid of a mattress after only a few years of use because we could not turn it! The springs wore out in that spot so that there was a "bowl" where one most laid. Not being able to turn it to re-position the mattress wore it out faster.

Grrrr!

I grew up in the days when it was only turnable matresses you could buy and they lasted a long time, in fact the current mattress I have is around 12 years old and still in usable condition and it is a turnable masstress, although I do want a new one and it will be turnable

No Turn Mattress

A turnable mattress is best because it helps to even out the wear and tear over the years . Get a decent pocket sprung one and it will last 20 odd years .

Turnable mattress is always a better option over no turn ones. They provide better way of living standard and is always favored by many. Go for it.
